Charmaine is putting money into a savings account. She starts with $350 in the savings account, and each week she adds $40. Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Charmaine has been adding money.
Write an equation relating S to W. Then use this equation to find the total amount of money in the savings account after 17 weeks

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
